Abstract

In the present study, cheeses coagulated with different milk-clotting enzymes were investigated. In detail, calf rennet, microbial coagulant, and a kiwifruit enzymatic extract were used in three independent cheesemaking processes. Microbiological, chemical, and sensory profiles, by using E-Eye, E-Nose, and E-Tongue platforms, were evaluated. Based on microbiological data, mesophilic bacteria, Lactobacilli, and Lactococci showed similar viable count in cheeses clotted with animal rennet and with vegetable coagulant. Differently, higher value of mesophilic bacteria and lower count of both Lactobacilli and Lactococci were detected in samples obtained using microbial coagulant. Additionally, as revealed by the fatty acid composition, the kiwifruit enzymatic extract allowed to obtain a final product with improved health properties. Concerning the artificial senses, E-Eye, E-Nose, and E-Tongue, a similar sensory profile was revealed among cheeses clotted using the kiwifruit enzymatic extract and the calf rennet whereas a different sensory profile was observed in microbial clotted cheeses. This work demonstrated that the kiwifruit extract is a valid coagulant alternative to calf rennet and microbial coagulant.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A high MCA/PA ratio results in the formation of short peptides, which impart sour and bitter flavors.

    “The high MCA/PA ratio results in the formation of short peptides, which impart sour and bitter flavors, with bitterness in cheese primarily resulting from the buildup of small hydrophobic peptides formed through the action of coagulants, especially rennet alternatives or microbial enzymes (Ayana et al., 2015;D'Incecco et al., 2022;Di Rosa et al., 2024).”
  • The addition of B. stearothermophilus and fungal coagulants contributes to the development of bitter taste in the cheeses produced.

    “Moreover, Di Rosa et al. (2024) explained that the addition of B. stearothermophilus and fungal coagulants contributes to the development of bitter taste in the cheeses produced.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
